Lateral load on Helical Piles

Lateral load on Helical Piles

Lateral load on Helical Piles

(OP)
I have seven helical piles on grade beam. The lateral load from column is acting along the length of the grade beam. The soil 7 ft underneath has very stiff clay. Would assuming the localized bending of helical piles will not occur be appropriate in this case?

RE: Lateral load on Helical Piles

Do you mean the grade beam is supported on helical piles? (The post says "helical piles on grade beam")
If you have lateral loads applied to the grade beam, which is in turn supported laterally by helical piles, then the helical piles will be subject
to shear and bending (and presumably vertical loading as well).
The extent of the shear and bending will depend on the soil and pile properties. An L-pile analysis could be used to determine those forces.
